Is GNU Affero GPL v3.0 or later compatible with Mozilla Public License 2.0?

No

GNU Affero GPL v3.0 or later is strong copyleft; combining it into a Mozilla Public License 2.0 project would force the combined work to be GNU Affero GPL v3.0 or later (not Mozilla Public License 2.0). If your project must remain Mozilla Public License 2.0, avoid GNU Affero GPL v3.0 or later code.
